HINGE.

Application filed November 13, 1922. Serial No. 800,615.

The present invention relates to a sprin'g door hmge, and. the object of the invention is to construct a hinge such. that'the hinge parts may be separated by removal of the pivot pin wthout disturbing the spring, so that when it is desired to unhang a, door which is mounted by the hinges forming this invention, it will only be necessary to remove the pin of each hinge, and the door may be readily removed while leaving the other part of the hinge in position for replacement of the door when desired.

Hinges of this character are particularly useful in the matter of hanging screen doors where it is undesirable to remove the screws from one of the parts of the hinge when it is desired to remove the door.

Reference should be had to the acc01npanying drawings forminlg a part of the specification, in which Fig. 1 is an elevation of the hinge; Fig. 2 is an elevation of one part of the hinge; Fig. 3 is an elevation with portions in section of the other part of the hinge; Fig. 4 is an elevation of the pivot pin by which the hinge parts are pivotally secured together; Fig. 5 is an end elevation of the part shown in Fig. 3; Fig. 6 is a transverse section of the art shown in Fig. 3; Fig. 7 is an end e evation of the part shown in Fi 2.

Referring to the rawings, one of the hinge parts is designated at l, and the other is designated at 2. The hinge part 1 comprises a flat base portion 3 which has a cut out integral tongue member which is rolled into a substantially cylindrical memher 4- having a slot 5 formed therein in substantiall the central part, as clearly indicated in Fig. 3. There are also end pieces 6 which are preferably formed by severir g and bendin up a portion ofthe blank from which this hinge art is formed. In fact, the construction w ich has so far been described can be formed as a stamping, and

the portion 4 turned into its substantially cylindrical shape, and the end members 6 severed from the blank and bent into the position in which they are shown in Fig. 3.

The portion 4 is so bent that the inner edge of this portion is slightly spaced from the body portion 3. Within the cylindrical ortion 4 and between the side or end memher 6 there is a resilient member which in the present instance takes the form of a spring, and preferably there are two sprin gs within this housing or member 4, each spring, such as the spring 7, being a cylindrical helical spring having one end 8 of the spring extending out from the portion 4 and bearing against the member 1, while .the opposite end 9 of the same spring will bear against the bottom of the slot 5.

The helical spring 10 with its free ends 11 and 12 is made and mounted in precisely the same fashion as that described. The other member 2 of the hinge has a fiat body portion 13 with upturned ears 14 and 15 which are spaced a art and parallel, and these cars are provided with openings, one of which is indicated at 16. The s ace between the ears 14 and 15 is but slig tly greater than the length of the member 4 on the other part of the hinge, so that when the two parts of the hinge are assembled the portion 4 and the end members 6 of the hinge part 1 will extend between the ears 14 and 15, and the holes in the end members 6 will align with the-holes in the ears 14 and 15.

It should further be noted that the helical springs 7 and 10 are in line with the holes in the members 6 and 14 and 15, so that when the members are assembled a pin 18 ,may be passed through the openings just described and through the central portion .of the helical springs 7 and 10. In bringing these hinge members 1 and 2 together 'the free ends 9 and 12 of the springs are above the plate 13 of the hinge part 2.

\Vhen the pin has been inserted then the hinge parts are pivotally mounted with respect to each other, and the hinge parts may be moved toward each other as the pivotal pin 18, thereby placing the spring under tension. 1

In applying the invention one of the hinge parts may be carried by a door frame and the other of the hinge parts carried by the door, there being suitable screw ornail holes provided for this purpose in each of the hinge parts, as indicated at l and 2. When the door is opened the hinge parts move relatively about the pivot pin 18, and the spring is compressed so that when the door 1s released it is moved back to its initial position.

By simply removing the hinge pin of each hinge the hinge parts may be separated and the spring element is definitely retained in its position, so that when the door is again to be hung the hinge parts are brought into their proper relation, as before described, the pin 18 reinserted in proper position in each of the hinge parts, and the door is ready for operation.

Having described my invention, I claim 1. A hinge comprising two members, means for detachably and pivotally connecting said members, and means for yieldingly opposing a relative movement of the members about their pivot from a normal posi tion and for returning the same to normal position comprising a coil sprin permanently mounted on one of the mem ers, said spring havin one end fixed to the member on' which it is mounted and the other end projecting over and bearing against the other hinge member, the hinge member on which the spring is mounted having means for retaining the spring thereon and for limiting the unwinding movement thereof, said means comprising a cylindrical portion fixed on one of the members entirely enclosing the coils of the spring to retain the spring and having a circumferentially extending slot through which the projecting end of the spring extends, said slot permitting movement of the projecting end of the spring upon a relative pivotal movement of the hinge members and so disposed that one end thereof is engaged by the projecting end of the spring when the members are disconnected whereby the spring is retained under normal tension.

2. A hinge comprising two sheet metal members, said sheet metal members each having a base portion and upstanding pivot portions, one of said members havin its inner edge portion rolled back upon itself to form a cylindrical portion along its inner edge lying outside the plane of its base portion, said cylindrical portion having a slot in its wall extending circumferentially from substantiall the plane of the base portion on the si e toward the other hinge member, a coil spring enclosed by and retained within said cylindrical portion, said spring having one end fixed to the hinge member upon which it is mounted and its opposite end projecting through the slot and normally engaging the base of the slot when the members are separated whereby it is retained under tension, and means for detachably pivot-ing the sections for pivotal movement substantially about the axis of the cylinder, the end of the splin projecting through the slot being engageable with the other hinge member and movable in the slot to yieldingly resist relative pivotal movement of the hinge members in one direction and to return the hinge members to normal position, and said members being separable one from the other or attachable one to the other without disturbing the spring or releasing the tension thereof. I

3. A hinge comprising a member having a body portion and spaced ears upstanding therefrom, said ears having aligned openings, a second member having a body portion and an integral fixed cylindrical portion ada ted to be positioned between the ears of t e first member to alignment with the openings thereof, said cylindrical portion having a circumferentially extending slot in its wall, a spring enclosed by and retained within said cylindrical portion, said spring having one end secured to the second member and its opposite end projecting throu h the slot when the members are separate and normally engaging an end of the slot whereby it is retained under normal tension, and a. removable pin pivotally connecting the sections, said pin extending through said ears and cylinder and through the spring within the cylinder, the projecting end of said spring engaging with the first mentioned hinge member whereby the spring Will be flexed upon movement of said member in one direction about its pivot and will yieldingly resist such pivotal movement, said members being separable one from the other when the hinge pin is removed and adapted to be fitted together to receive the hinge pin without disturbing the spring or releasing the tension thereof.

i. A hinge comprising a sheet metal member having a base portion and an edge integral portion turned outwardly and back 1041* upon itself to form a cylindrical portion and ears struck u from the base portion closing theends of the cylindrical portion, said ears having openings therein, said cylindrical portion having a circumferential 1 slot in the wall thereof extending outwardly from substantially the plane of the base at the outer side of the cylindrical portion, a coil spring mounted within the cylindrical portion, said spring having one end secured 11 to said member and its op osite end rojecting through the slot a normally old by the tension of the spring against the base of the slot when in use, a second sheet metal member having a body portion and 115 spaced ears upstanding therefrom adapted to receive between them the ears and cylindrical portion of the first member and having openings adapted to align with the openings in the ears of the first member and 120 a removable pivot pin passing through the ears of the two members, through the cylin-' drical portion of the first member and through the spring, the body portion of the first member being engageable with the pro- 125 jecting end of the spring to shift the same outwardly in the slot of the cylindrical portion whereby relative pivotal movement of the members out of a normal position is yieldingly resisted by the spring and the spring acts to return the members to nor mal position and said members being separable without disturbing the spring or releasing the tension thereof.

5. A hinge comprising a member having an integral cylindrical ortion along its inner edge, said cylindrical portion having intermediate its ends a circumferentially extending slot, a air of sprin s enclosed by and retained wit in the cylindrical member said springs having their outer ends fixed to said member and their inner ends rojecting through said slot and normally eld by the tension of the springs against an end of the slot when the elements of the hinge are separated, a second member having spaced upstanding ears ada ted to receive between them the cylindrica portion of the first member and having openings adapted to be aligned with the cylinder, and a removable pivot pin passing through said ears, through the cylinder and through the springs within the cylinder, said second member having a portion engageable with the projecting end of the spring to shift the same in the slot upon a relative pivotal movement of the hinge members in one direction whereby the springs act to yieldingly oppose pivotal-movement of the hinge members from a normal position and to return the hinge members to normal position, said hinge members being detachable one from the other without disturbin the spring or releasing the tension thereo 6. hinge comprising two separable members, each having extending parts with openings which are adapted to align, a removable pivot pin extending through said openings, a pair of coil springs through which the pintle extends, each coil spring having its opposite ends bearing against the respective hinge members, and means integral with one of the hinge members for partiall incasing the springs and for limiting t e unwinding movement of the springs when the hinge members are separated.

7. A hinge having two leaves, each having ears extending therefrom with pivot pin openings therethrough, a removable pivot pin arranged to extend through the openings in the ears, the ears of one leaf being arranged to be received between the ears of the second leaf, a sprin retainer fixedly connected to the first lea a helical spring in the retainer being held therein against any substantial radial movement relative to the axis of the pin openings or along said axis, one end of the spring being arranged to exert pressure on the second leaf when the leaves are connected by the pin and the leaves are in theirnormal swinging positions, and a fixed stop on the first leaf in the line of movement of the last mentioned end of the spring to prevent unwinding thereof if the leaves are disconnected or if the leaves are moved beyond a predetermined limit in one direction.
